All, for a practical application, here is the results of my nanoVNA setup
from my shack into a Butternut HF-6V antenna.  This was not calibrated on
each band so some of the TDR results are off.  The actual distance is about
60 feet of Belden RG8.

 

The Butternut is hard to tune because of the coil design and because I have
this mounted on an awning pole about 10 feet high with no radials.  

At the antenna, it looks a bit better but my key problem is 5:1 SWR on 20m
which is the band I'm usually working.  Works very good on 6m also. 

 

Unit is a Nano VNA with a 2021 build date v 1.0.71.  Software is NanoVNA
Saver v 0.5.5 0.
